Let's start with the crown jewel of the bundle, the program that's most likely to make your wallet spring open: Parallels Desktop 7. A $79 program all by itself, Parallels lets you run Windows 7 and Windows programs on your Mac, no rebooting required. It's a top-rated utility, and with good reason.

Even if you buy Parallels from, say, Newegg, you'll pay around $60, which is $10 more than the bundle costs. And, let's not forget, iStack comes with nine other items.

Among the highlights: Snagit, a popular screen-capture utility; PaintSupreme, an image-creation and image-editing tool; Disk Drill Pro, which helps you recover lost data; and iGlasses 3 for fine-tuning Webcam images.

Of particular interest is Udemy's iOS App Development Video Course, which teaches you everything you need to know about designing and launching iOS apps. It typically costs $499 all by itself.
